BACK STRAIGHTENER.

Application filed October 15, 1924. Serial No. 743,779.

'10 all whom it may concern:

Be it known that I, JoHAN ERNST NYnor, a subject of the King of Denmark, residing at Copenhagen, Denmark, have invented certain new and useful Improvements in Back.

Straighteners, of which the following is a specification.

The present invention relates to a backstraightener, i. e., a device adapted to be applied on the back of aperson in order to support and correct the spine and to give him an erect hearing.

The back-straightener according to the present invention is characterised by two comparatively narrow plates each comprising two branches of almost right angular shape with rounded edges, the longer arms of which face each other and extend upwards. Near their upper ends these plates are connected together by alink. The angular plates are of such a construction that they substantially coincide with the scapulae or shoulder blades. Each of the substantially horizontal arms, which are directed towards the arm pits, is provided at its end with a strap or elastic band to pass under the arm and up to the top of the vertical portion where it can be tightened by means of a buckle.

A constructional form of the backstraightener according to the invention is by way of example shown on the drawing wherein,

Fig. 1 is a front view of the back-straightener, and

Fig. 2 is a rear view of the back-straightener as applied on the person.

1, 2 are the aforementioned narrow plates.

each consisting of two branches 1 and 2 bent in a curve at approximately right angles to one another. The two branches 1 are near their outer ends interconnected by a link 3, a buckle 4 being provided at the outer end of each of said branches 1. To the outer end of the branch 2 of each plate there is connected an eye 5 to which is secured the one end of an elastic band 6, the other end of which can be connected to the buckle 4 of the respective plate (1, 2).

The device is secured on a person as shown in Fig. 2. As will be seen from this figure the branches 1 of the two plates extend approximately parallel to one another in the longitudinal direction of the back, each branch resting on the respective part next to one another of the two shoulder-blades, while the branches 2 extend laterally and approximately horizontally resting on the lowermost part of the respective sh0ulderblades. The link 3 connecting the two branches 1 to one another will assume a position across the back as will be seen from the figure. The elastic bands 6 are passed below the arms of' the person and up above the shoulders and are connected each with a buckle 4 as will appear from Fig. 2.

In the manner described each plate (1, 2) will follow the movements of the respective shoulder-blade and the interconnection between the two plates by means of the link 3- and the presence of the two elastic bands 6 under the arms Will result in that the shoulder-blades, under the influence of the plates acting as levers, will be pressed forward with a considerable force the shoulders being at the same time forced backwards so as to give the person an erect bearing. As a consequence of the arrangement and manner of applying the device, the user will feel no captions sensation.

I claim:

1. A spinal or back-straightener comprising a pair of angular plates; a single link pivotally connecting said plates together; and a band for each plate for securing said plates to the shoulder of a wearer.

2. A. spinal or back-straightener compris ing a pair of angular plates; a single link for connecting said plates together and being pivotally connected thereto; and means for securing said plates to the shoulder of a wearer.

3. A spinal or back-straightener comprising a pair of angular plates; a single link pivotally connecting said plates together; a band secured at one end of each plate; and a buckle secured at the other end of each plate, said plates being adapted to be secured to the shoulder of a wearer by means of the bands and buckles.

In testimony whereof I affix my signature.

JOHANOERNST NYROP.
